Fuel Injector · 模型 70162
A fuel injector is a precision mechanical and electromechanical assembly designed to deliver a controlled amount of fuel into an internal combustion engine. It plays a critical role in engine performance, fuel efficiency, and emission control by atomizing fuel into fine droplets and injecting it at the correct time, pressure, and spray pattern. Fuel is delivered under high pressure from the fuel pump to the injector. When the ECU sends an electrical signal to the injector, the solenoid or piezo actuator lifts the needle valve against spring force. This allows fuel to pass through the nozzle, where it is atomized and sprayed into the combustion chamber or intake manifold. Once the signal stops, the spring forces the needle back to its seat, stopping fuel flow.
